What's your handle on Pirate? Do you hang out in the OSR? I'm an IH guy, but I hardly ever go to that forum anymore.
For me it's mostly Pirate and Bayoushooter, THR has good info, especially for more obscure stuff. I'm also a member at The Binderbulletin, some motorcycle forums, I think I'm a member at weaponeer, I lurk at arfcom a little, mostly to laugh that the Larue fanboys.

XDtalk.com (What can I say, I'm a fan!)
rcgroups.com (All things RC - I fly helis and planes)
+ Various video game forums, depending on what I'm playing at the time.
